These improved LFP graphene batteries could charge at 10C and discharge at 20C for 1000 cycles with only under 15% capacity decay rate. To better understand this, if a battery is rated at 1200 mAh, this means that it can, in theory, provide 1200 mA of current for one hour.
Graphene battery applications. Conventional electric car batteries take a long time to fully charge - up to 5 hours in some cases. Even at full charge, they offer a range of only about 50 miles in some cars. Graphene batteries could offer the same range, but the charge time could be reduced to under half an hour.
Improved discharge rate means that graphene batteries have a higher maximum power output. Graphene batteries are new technology and as of 2013, they are just entering mass production. This means that they are still under research. Optimal manufacturing processes are yet to be discovered.
Maximum Continuous Discharge Current – The maximum current at which the battery can be discharged continuously. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity.
Graphene batteries are made by enhancing existing Li-Ion batteries. This is achieved by enriching the electrodes with graphene which changes their chemical and physical properties. The results are improved charge/discharge rate characteristics as well as improved capacity.
Maximum 30-sec Discharge Pulse Current –The maximum current at which the battery can be discharged for pulses of up to 30 seconds. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity.
